Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent dust and insects from getting in a control box by providing a guide for inserting a filter into an opening and an elastic member which is adhered closely to the control box in the guide. SOLUTION: A control box 1 provided with a filter 21 is set up in an ice making machine room provided with a cooling device and the roof plate 2 of the box 1 which is put on the box 1 as a cover has an opening for ventilation. A guide 4 which is used for inserting the filter 21 into the opening 3 is attached to the roof plate 2 so as to cover the opening 3.

Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To reduce a labour and a cost needed for exchanging an abraded punch and, improve safety as well in a tool for punching a hole on a work by reciprocating a punch. SOLUTION: A blade 7 is provided with a piston 5 which reciprocates within a cylinder 4 and, a punch 8 is fastened with the tip of the blade 7 by screwing-in.
